MILK-STRAINEE.

SPECIFICATION forming part of Letters Patent No. 659,672, dated October 16, 1900.

Application filed June 20, 1900. Seriallllo. 20,913. (No model.)

To all whmn it may concern:

Be itknown that I, FREDERICK HEYL, a citizen of the United States, residing at Irvington, in the county of Essex and Stateof New Jersey, have invented certain new and useful Improvements in Milk-Strainers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to secure greater efliciency and quickness in straining the milk and to prevent clogging because of an accumulation of sediment settling upon the top of the straining cloth or diaphragm as heretofore, to enable the strainer to be cleansed with greater facility and case after straining, and to secure other advantages and results, some of which may be referred to hereinafter-in connection with the description of the working parts.

The invention consists in the improved strainer for milk and other fluids and in the arrangements and combinations of parts of the same, all substantially as will be hereinafter set forth, and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like letters of referenceindicate corresponding parts in each of the views, Figure 1 is a plan of my improved strainer, certain parts thereof being broken away to iliustrate the construction more clearly; and Fig. 2 is a vertical section of the same, taken on line 00.

In said drawings, a indicates a funnel-like body, made of tin or other suitable material and having inserted at its smaller lower end a vertical pipe or tube 5, which extends interiorly upward an inch, more or less, from the bottom of said funnel-like body. Said tube may be fastened in position by means of solder or in any suitable manner. The upper end of the said tube is exteriorly threaded, as at b, and is provided at the lower end of the threaded part with a shoulder b for limiting the downward movement of the straining-cup. Said tube may be in two pieces soldered .together or otherwise. Upon the said upper end of the said threaded tube is screwed the strainer. This com prises an open portion 0 is provided with a female screw adapted to engage the upper threaded end of the tube 1), and said hub extends a limited distance, as at 0 upward above its spokes and is exteriorly threaded, as at c, for a purpose hereinafter described. Upon the frame 0 formed by the hub, connecting-spokes, and circular rim 0 is seated a straining-disk d of fine wire-cloth, cotton cloth, or other suitable straining material. This straining material forms the bottom of the cup and is held in place by an open wheel-like Washer ornut e, which is provided with threads at its perforated cent-er, adapted to be screwed upon the upper extension 0 of the threaded hub. The wheel-like nut e is screwed hard upon the wire network or straining material, clamping the same rigidly and firmly in position, but said network is permitted an easy removal for purposes of cleansing or repair.

The cup-like strainer when screwed upon the upwardly-extending tube 1) does not at the periphery extend down into contact with the flaring sides a of the body, but a passage a is formed between said cup-like part and the funnel, so that there is a free passage of milk downward therebetween. At the top of the cup is arranged a cap f, which may be fastened upon the body or flange of the cup by means of a bayonet joint connection, lock, or catch, or in any other suitable manner, the joint between the flange 0 and the said cap being substantially impervious to milk. The said cap f at its interior center lies a little above the upper end of the tube 1), so that there is a clear passage and communication between the cap-chamber and the passage through said tube, and thus in operation the milk supplied to the funnel-like body a passes downward through the passage a between the cap and the said funnel, and thence passes upward through the openings in the frame 0 and through the straining-cloth or network, so that all extraneous matter or sedimentitious matter is prevented from passing upward. This matter gravitates to the small bottom end of the funnel. The strained milk then flows into the cap and downward into the upper end of the tube and thence outward from the strainer. will not clog the under side of the cloth ril to a material extent, as in the straining opera- Lions heretofore practiced, but will gravitate The heavy sedi [1161111 to the small end of the funnel away from the cloth, and thus can be very easily removed after the milk-straining operation by Washing or by other means.

Having thus desori bed the invention, What I claim as new is 1. The improved milk-strainer, comprising a funnel having a tube fixed to its bottom and extending into the interior thereof, aeu p removably secured upon said tube and having an open bottom, a removable cover for the open top of said cup, and a straining-diaphragm removahh fastened across the opening in the bottom of the cup, substantialb as set forth;

2. The improved milk'strainer, comprising a funnel having-a tube fixed to and extending up f-nom the bottom off said funnel an open frame 0, having an upward flange 0 a straining-diaphragm resting on said open frame, means for clamping said diaphragm upon said frame, and a cover, all arranged substantially :as set forth.

3. The improved strainer, comprising a tunnel having a tube at the bottom, said tube having at its upper end a clamp in which a straining-diaphragm may be renlovably secured, said diaphragm beingar-ranged around the open end of said tube, and a cover removablyar-ranged over-said diaphragm and open end-of the tube and preventing a flow into said tube except through said straining-diaphragm, substantially as set forth.

In testimon5 that I claim the foregoing I have hereunto set my hand this 6th day of June, i900.

FREDERICK HEYL.
